According to a recent report, the Samsung Galaxy Z Flip4 would get a modest battery capacity improvement.
Now that the real batteries have been photographed, it appears that the change will be more extensive than anticipated.
Samsung SDI manufactures both of the batteries. One has a capacity of 2,555mAh, while the other has a capacity of 1,040mAh.
This raises the total capacity to 3,595mAh, however the typical capacity will most likely be 3,700mAh. That’s a 400mAh boost over the Z Flip3 battery, or a 13% increase in capacity.
